My daughter has a lymphatic malformation at the base of her tongue and above her epiglottis-she experiences severe pain even though the lesion has been shrunk significantly with sclerotherapy injections. This week we are attempting a glossalpharangeal nerve block to attempt to alleviate her severe pain. Thank you for the lesson so I can better understand her diagnosis and treatments!
How is your daughter doing now? I hope she doesn’t have pain anymore
I hope your daughter is feeling better now. Sending lots of love 💖💖💖❤️🩹❤️🩹❤️🩹💞💕💟💖💓💘💓🩵💙❤️💛💚🧡
Lmao this guy is way better than our medical professors.
+Mahdi Katz lol!! I'm so happy we were able to help!!!
@@NinjaNerdOfficial I am one of your biggest fans and your videos helped me alot , but there is a mistake in this video and the vagus nerve video. the glossopharyngeal nerve innervates the carotid body and sinus by (GVA) fibers so it transmits information about blood pressure to the medulla and here comes the vagus nerve role where it transmits those informations to the cardiac plexus by (GVE) fibers causing a change in heart rate according to the blood pressure state. ... or am I the one getting it wrong ? I will be glad if you answer my question.
@@sarahu.k7162 Siegel (book) also mentions that, but it seems he focused only on the taste function...
Respect your teachers...
My professor tells me to watch Ninja Nerd videos 😅😅
Ur much better than others in RUclips and I'm sure u will be next Dr najeeb sir love from India
+Subhash Naik wow thank you so much for your super kind words. I truly appreciate it!
Quite frankly, I think he's already better than dr. najeeb
Being an addict of NEUROLOGY, in my views he is much better than sir Najeeb. For me at least.
@@Peter-jx6qq yes najeeb is a scam artist
Lol,In the first impression, he looks like a Gym trainer😂😂, but later he proves that he is far better than our professors
It's darkly hilarious that this guy can record a 30 min vid without mistakes in writing, drawing and speaking.... so perfect
All concepts are crystal clear now! Woah!
I am sooo happy that people have access to your knowledge. You are awesome 😭
I have a Subependymoma in my 4th ventricle sitting on top of my Glossopharyngeal Nerve... Basically every thing you point out in this video feels like it's burning to me. This was great, because it makes what's going on a lot more understandable.
did you do surgery and if so are you okay now?
tysm it was really helpful but can u please take a picture(whiteboard) in the end and add in the description below.. it would really be helpful
How do you make every topic that interesting ?? Seriously man you are amazing 😅😅
OMG i am in love the way you simplified such a messed up thing..!!!
Palatopharyngeus is the muscle of the soft palate while stylopharyngeus is the muscle of the pharynx. Nice presentation.
Wow! You have helped me learn a lot Zach/Ninja Nerd Lectures! And you continue to help me learn more! Thank You for teaching us! It feels pretty sweet to be learning; and to actually, truly, be understanding what is being taught! You help me feel good; it’s pretty dang nice! Thanks again! Ninja Nerds for Life!
Better than any classroom or clinical presentation in my training!
YOU ARE LITERALLY THE BEST.
Video is great. Simplified my quick revision for exams. Thank you. But just a small point ..Stylopharyngeus is the muscle of pharynx.
I swear I think I love you! Saving my life university please never stop!!!! You are our Gregory House
Thanks a lot for sharing ur passion and knowlege with us ! But the fungiform papillae gets innervation from the chorda tympani. The glossopharyngeal nerve gives supply to the papillae foliatae. :)
exactly, well said
Best explanation ever !! You made the whole topic very simple and the easiest to learn and understand... Thankyou !!
Appreciable work, the way of teaching is pretty good. Makes a lot of sense. Thank you sir
Thank you. Very articulate and clear explanations.
you are saving lives of students
Thanks too much . Your follower from Egypt
thank you... nice video ..... just wanna clear one point stylopharengeous is muscle of pharynx
Good one. Thumbs up for effort.
Very informative with detail descriptions.
Very useful, simple and clear~!
Amazing explanation sir......just love the way to put things simply.
you are the best teacher❤❤❤
Congratulations for your work. Greeting from Colombia.
Is there a pdf of jpg file of your entire schematic presentation of this lesson? :)
Have you find it?

This guy is AMAZING
I enjoyed watching your video. I have glossopharyngeal neuralgia. Back in 2003 I had brain sure to help relieve the pain. I have other symptoms and was not sure why. But since I watch your video I now understand that they come from the G nerve. We call them my G attacks.
N glossopharyngeus is picking up gustative sensations from papillae vallatae and foliatae not fungiformes if I'm not wrong. For fungiformes it should be n intermedius (VII)
+Dragana Trifunovic have you seen our video on gustation. Check it out!!!🤓
I think so
Definitely I agree with you. fungiform papillae through intermediate nerve and CN VII
If I'm not wrong otic ganglion is present below the foramen ovale
From 22:30 he says touch, pain & temperature fibers of GVA, but isn't touch, pain & temperature sensations usuallly GSA ( general somatoafferent) fibers? And GVA fibers are responsible for the taste sensation from the tongue?
True, he also made a mistake with the papillae fungiformes, they are found in front of the sulcus terminalis and are connected with the facial nerve not the glossopharygeal
No taste is SVA
Taste is special sense.
Sweet stinkin deal! Roasted! Thank you Zach. Thank you Ninja Nerds.
Thanks for being a awesome Ninja Nerd!
I love this channel so much I like the videos before i start them even
The best teacher , thank you
Thank you for this wonderful video!! I have a reporting tomorrow via web meeting and this video really really helped me.
Stylopharyngeus is a muscle of the pharynx not the soft palate
U r at the top sir .
This is so niceeeeee😫 like it just simplified glossopharyngeal nerve for me.
This is so helpful! Thank you so much!
very complex topic .... very nice explanation
Isn’t that posterior 1/3 tongue does not have papillae,they only have lingual tonsil??
Superbly done 👍👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
very good presentation, enjoyed it. Very thorough.
+Amey Sharma Thank you so much for you kind words and I'm so glad you enjoyed it!!!
wouldnt the fibres from the carotid body and sinus be considering special visceral afferent (though i know its not like a specific sense - then would make sense why they would go to tractus solitarius) also, in my instant anatomy booklet it says the GVA fibres from the pharyngeal mucosa, tonsils and tongue go to the sensory nucleus of V ???? which one is correct?? (there is no mention of that vagus nucleus in my book)
Hey there. About your question on why aren´t the fibers from the carotid body and sinus considered special visceral afferent I think i can explain that to you. Those types of fibers include things like the sense of taste and the sense of smell. From what i read in my text books those are the only examples
Hope I helped :)
Wow 😮,,, selected after Dr Najeeb 💝💝🌹🌹🌷🌷❤️❤️❤️❤️❤️
Great talk, I watched three times.
These videos are AWESOME!
I’m so happy because of you
Great explaination
Sir otic ganglion is present below the foramen ovale but u draw anteriolateral to pterygopaaltine fossa
Love your lectures 😍😍
you r god of science luv u bro
The name checks out.
😎👍🏻
Thanks for the presentation.
+Aditi Dev so happy we were able to help!
thank you
This lecture was bomb! Thank you so so much :)
Love this channel!
T
hank you Zach!
lesser petrosal isnt only presynaptic fibers? i think that auriculotemporal gives the postsynaptic fibers?
Quite amazing & helpful video .....!!!!!!thank you sir.....🌝🌝
There was no mention of Tympanic nerve arising from Inferior Petrous Ganglion ????
You are the best♥️♥️♥️
great work, keep making more such videos.
+Nerd Xl thank you so much I'm so happy that we were able to help!
And they say there's no Creator. That is awesome!
Thanks a lot
Does the glossopharyngeal nerve supply the dura mater? seen some websites saying the opposite
ur amazing man, THANK YOU
is glomus cells found inside carotid bodies?
Well explained thx lot
Thanks❤
Hi, Dr Murphy, how have you become pro at anatomy? Give me some tips pls. I am a second year MBBS student
Very helpful !!! 👍
Tkank you very much
Great explaination sir.. :)
Would like to get more vedio on neurology :)
+sanskriti gupta Thank you! We are trying to!
You're welcome sir 😊
Your vedios helped me alot .. :)
great video
Thank you so so so so much :D:D
respect u sir........
cheers
I dont quite get it. Does the nerve from Inferior salivatory nucleus exit foramen jugulare and formanen ovale?
+Alexander Top Marchant Great question! The glossopharyngeal nerve does exit the posterior cranial fossa through the jugular foramen. However there are certain fibers that make up the glossopharyngeal nerve. One of these fibers are called GVE fibers which are parasympathetic fibers. Once the GBE fibers move out of the posterior cranial fossa via the jugular foramen. The GVE fibers next enter into the middle ear cavity through the tympanic canaliculus then from there it moves up onto the promontory of the middle ear where interacts with some of the sympathetic fibers that branch off of the carotid plexus. From that point on these parasympathetic fibers(GVE fibers) move up into the middle cranial fossa through the hiatus of the lesser petrosal nerve then the lesser petrosal nerve(which are still GVE fibers of the glossopharyngeal nerve) moves out of the middle cranial fossa through the foramen ovale. it will progress until it reaches what's called the otic ganglion. From there postganglionic parasympathetic fibers(GVE fibers) progress until they reach the parotid gland. Where they will stimulate salivary gland secretion. Does that clarify your question?
Yes! Thank you very much! These videos are SO helpful for my neuroanatomy exam! Great work!
Sweet Deal!
I thought fungiform papillae were supplied by a facial nerve. In detail by chorda tympani.
Wow, I like the Penn State Hat. You really know your stuff. My husband is a two tour Vietnam Vet. Guess what, Agent Orange plus. I listen to you vagus nerve and most. Fabulous! Thank you.
We thank him for his service!
Great
Thanku so much
Great video. How can I ask a question to instructor?
awesome
glossopharyngeal nerve innervates vallate and foliate papillae not fungiform
Make pharyngeal arches :)i know you can make it clear plz do consider ninja man
Nice I like it
#respect
This guy has not made video on triangles of neck😞😞
I LOVE YOU ❤️
the best
